Reliable detection of GABA is important for research studies in neuro-psychiatric diseases. In vivo 1H GABA resonances extensively overlap with the neighboring resonances of glutamate and glutamine. We present an optimized single-shot triple-focusing 1H MRS method which fully resolved GABA 2.29-ppm signal at 3T.
